The command "auditd -d" is used to start the Linux Auditing System (auditd) in debugging mode.

The Linux Auditing System allows you to monitor and record various system events and activities, providing valuable information for security and compliance purposes. The auditd daemon is responsible for collecting and storing audit events generated by the kernel.

When you run "auditd -d", it starts auditd in debugging mode. Debugging mode enables verbose output, which can help diagnose any issues or errors related to the auditd daemon. It prints detailed information about the audit rules, events, and actions being executed.

The debugging mode can be useful when troubleshooting or fine-tuning the auditing configuration. However, it may produce a large amount of output, so it is generally used for temporary diagnostic purposes rather than regular operation.

It's important to note that running auditd in debugging mode requires sufficient privileges, typically requiring root or administrative access.
